HEAD-LAMP.

Applicationfilefi October 8, 1916. Serial No. 123,551.

lamp by means of which the usual for-' wardly projected blinding rays of light are eliminated and said rays are directed downwardly upon the road surface in front of the machine equipped with the lamp.

A further object in view is to provide a novel arrangement of front panel, lamp and reflector whereby a forwardly diverging zone of illumination is provided for.

The lamp is so mounted that it may be tipped or tilted for the purpose of extending or directing the range of light in accordance with road and other conditions.

With the above and other objects in view, the invention consists in the novel construction, combination and arrangement, herein fully described, illustrated and claimed.

In the accompanying drawing:

Figure 1 is a perspective view of a head lamp embodying'the present invention.

Rig. 2 is a vertical fore and aft section through the same showing the relative arrangement of the front panel, the reflector and the lamp.

The lamp contemplated in this drawing resembles, in its broad aspect, a helmet such as is worn upon the head except that the bottom thereof is closed. In its normal position the front face of the lamp which contains the transparent panel 1 is inclined as clearly illustrated in both figures of the drawing and the shape 'of the front opening in the lamp, as well as the shape of the transparent panel 1, is substantially semicircular or in the form of a half disk with the straight side or edge 2 disposed upwardly.

The body or shell 3 of the lamp is provided at the rear semicircular portion 4 thereof with a movable section 5 corresponding in shape to the general outline or formation of the shell, said movable section 5 constituting a door or closure which may be opened to give access to the interior of the shell. As illustrated, the

projected upwardl movablesection 5 has itslower edge held in a rabbet 6 while the upper portion ofthe section 5 is securely held in place by any suitable fastening means. It will be apparent however, that the section 5 may be hinged to the shell 3' and be opened in the same manner as a door.

Secured to the inside face of the movable section 5 is a'" reflector 8 which resembles in shape, the shape of the transparent panel 1. The reflector 8 is, however, reversed in relation to the panel 1 or in other words the straight edge 9 of the reflector 8 is disposed downwardly while the straight edge 2 of the panel 1 is disposed upwardly.

The lamp 10 which ordinarily consists of an electric bulb, is located between the reflector 8 and thepanel 1 and is'farranged behind a curved reflecting wall or surface 10, the latter being therefore interposed between the lamp 10 and the panel 1. The curved wall or reflecting surface 10 extends preferably transversely all the way across the bottom portion of the shell v3 so that the rays of light from the lamp 10 are directed against the reflector 8 by which they are deflected and transmitted through the panel 1. The top edge of the panel 1 is preferably located slightly higher than the bottom edge of the reflector 8 but not sufliciently to permit the rays of light to be so as to blind or confuse trafic general y. 1

As shown in the drawings the lamp is pivotally supported between the uprights or standards 12 rising from a supporting base 13 which may be secured fixedly or in any desired manner to a convenient part of the vehicle. The upper extremities of the standards 12 are formed with openings or slots 14 to receive clamping members 15 shown in the form of headed screws which enables the lamp to be tilted or adjusted to diflerent angles for the purpose of illuminating the road way to any desired distance in front of the vehicle. A person standing directly in front of the vehicle does not see the direct rays of light from the lamp but can only see the light which is thrown directly upon the ound. Therefore there is no blinding e set but merely an illumination of the road surface.

I claim:

1. A head lamp comprising a shell having a normally inclined and downwardly facing orifice in the front thereof, a trans- Speciflcation of Letters Patent. 'Patpented 31, I917.- 1

parent panel contained within said orifice, a reflector on the inner surface of the rear portion of said shell, a source of light located between the transparent panel and said reflector, and a curved reflecting surface interposed between said source of light and the transparent panel, said transparent panel being substantially half round and formed with an upwardly disposed substantially straight edge, and the reflector being also substantially halt round and having its substantially straight edge disposed downwardly.

2. A head lamp comprising a shell having a normally inclined and downwardly facing orifice in the front thereof, a transparent panel contained within said orifice,

a reflector on the inner surface of the rear portion of said shell, a source of light located between the transparent panel and said reflector, and a curved reflecting surface interposed between said source of light and the transparent panel, said transparent e edge of the transparent panel being normally located slightly higherthan the substantially straight edgeot the reflector.

In testimony whereoflaffix my signature.
